Analysis

5d ago

This market shows extreme mispricing with a 2,859% implied yield on the Yes side, suggesting the 6¢ price significantly undervalues Republican chances in Maryland's 4th district, a historically competitive seat. The zero 24-hour volume combined with $21,218 open interest and a 2¢ spread indicates severe illiquidity, making the quoted price potentially unreliable and the high yield partly a liquidity premium rather than pure probability mismatch. The recent price decline from 7¢ to 6¢ over seven days warrants caution, as thin markets can experience sharp moves on minimal trading activity, and with 200 days to expiry, there's substantial time for regime shifts in this neutral-scored market.

Resolution rules

This market will resolve according to the party of the candidate who wins the MD-04 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The midterm elections will take place on November 4, 2026. ​A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democrat or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the House elections are conclusively called by this market's resolution sources. This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).
